Talk is a core Google app, it has been on my Monterra from the beginning. Talk functionality was integrated into Hangouts in 2013, it's not even being updated.
I've never gotten an error message about not communicating with google servers. You might want to:
- Turn off sync in Settings/Accounts & Sync
- Ensure that no backup or restore boxes are checked in Settings/Backup & reset
- Turn off Auto-update apps in Google Play settings
